I don't know much about any of them except Johnson. He's someone I'd target because he's got good power and speed. He also has a real good eye. His minor league numbers were pretty good as well. In 155 abs at AAA he had 34 walks but only 22 k's.

I don't have any data to back it up, but I seem to remember hearing good things about Shin-soo Choo. He was Baseball America's 51st best prospect on the 2005 list, a list which included everyday MLB players (Mauer, Reed, Francis, Swisher, Kazmir among others) and others who were called up partway through the season (Francouer, Weeks, Davies, Duke, etc.)
